PINNING THE DOOR

Note: A ballooning door may delay the safety reversal
response and can compromise garage door security.
• To remedy any ballooning place self tapping metal screws
or rivets where the curtain leaves the roll. Secure these
through the curtain into the drum wheel at each end of the
roll.
• After determining the correct fastener location as shown, lift
the door approximately half a turn from the closed position
to allow access for drilling.
